Federal regulations require CDL holders to transfer their license to a new state of residence within 30 days of establishing residency. The 30-day clock starts the day you become a resident — not the day you get a job, register a car, or open a bank account, but the day you take up actual residence.
What documents you need
Bring your current out-of-state CDL; proof of new-state residency (a lease, utility bill, mortgage statement, or bank statement showing the new address — most states require two pieces of recent dated mail); your DOT medical card; Social Security card or W-2 showing your SSN; and proof of legal presence (passport or certified birth certificate). If you hold a Hazmat endorsement, the new state will likely require a fresh TSA threat assessment in their state — your old TSA approval does not automatically transfer.
Knowledge or skills tests usually waived
Most states waive both the knowledge tests and the skills test for incoming transfers, provided your existing CDL is valid and unexpired. Some states require you to pass a state-specific written exam covering local laws (Texas, California, and a handful of others). Check your destination state's CDL handbook before booking your appointment.
Fees
Transfer fees range from $40 to $120 in most states. Some states charge an additional residency-establishment fee on top of the standard CDL fee. Hazmat re-add fees ($86.50 federal TSA + state fee) apply if you carry the H endorsement.
Old license must be surrendered
You cannot legally hold two CDLs simultaneously — the FMCSA's "one license, one record" rule prohibits it. Your old state will be notified of the transfer through the federal Commercial Driver's License Information System (CDLIS), and your old license will be canceled. If you've had violations on your old record, they transfer with the license.
If you're long-haul OTR
If your work keeps you on the road for weeks at a time, schedule your DMV appointment for your next home-time and use a knowledgeable family member or attorney to gather the residency documents in advance. Many states allow appointment-only CDL transfers that take under an hour — the bottleneck is usually paperwork prep, not DMV time.
